DETAILED DESCRIPTION

To make the objectives, technical solutions and advantages of thepresent disclosure clearer, the followings describe the embodiments ofthe present disclosure in detail with reference to the drawings.

In the related art, a 3D display device includes a display assembly anda motor and a driving assembly which are connected to the displayassembly. The motor can drive the display assembly to rotate, and thedriving assembly can drive the display assembly to display images. Thedisplay assembly displays images to present 3D images by usingpersistence of vision of human eyes during a process in which the motordrives the display assembly to rotate.

However, in order to enable the driving assembly to drive the displayassembly to display images, the driving assembly needs to be connectedto an external driving power supply over a power line in addition tobeing connected to the display assembly. The power supply line is notconducive to the rotation of the display assembly, leading a poordisplay effect of the 3D display device.

FIG. 1 is a schematic structural diagram of a display device accordingto an embodiment of the present disclosure. As can be seen from FIG. 1,the display device 10 may include a display assembly 101, a hollowhousing assembly 102, a motor 103 and a driving assembly 104.

The display assembly 101 is disposed within the hollow housing assembly102. The motor 103 is connected to the display assembly 101 andconfigured to drive the same to rotate. The driving assembly 104 may beconnected to the display assembly 101 and configured to drive the sameto display images. In this way, when the motor 103 drives the displayassembly 101 to rotate, the driving assembly 104 drives the displayassembly 101 to display images, thereby achieving a 3D image effect.

Referring to FIG. 1, the driving assembly 104 includes a wireless powertransmission structure 1041 and a wireless power reception structure1042. The wireless power transmission structure 1041 is independent fromthe display assembly 101 and wiredly connected to a first driving powersupply. The first driving power supply is configured to supply power tothe wireless power transmission structure 1041. The wireless powerreception structure 1042 is wiredly connected to the display assembly101, and the wireless power transmission structure 1041 is capable ofdelivering power to the wireless power reception structure 1042 byelectromagnetic mutual inductance. In this way, the wireless powerreception structure 1042 can deliver received power to the displayassembly 101, such that the display assembly 101 can display images.

Since the wireless power reception structure 1042 is wiredly connectedto the display assembly 101, the wireless power reception structure 1042can rotate synchronously with the display assembly 101 when the motor103 drives the display assembly 101 to rotate. The wireless powertransmission structure 1041 independent from the display assembly 101does not rotate synchronously with the display assembly 101. In thisway, the driving wiring that connects the first driving power supply andthe wireless power transmission structure 1041 does not influence therotation of the display assembly 101, thereby ensuring a display effectof the display device.

In summary, according to the display device provided by an embodiment ofthe present disclosure, a wireless power transmission structure candeliver power provided by a first driving power supply to a wirelesspower reception structure by electromagnetic mutual inductance, and thewireless power reception structure can further deliver power to adisplay assembly. Since the wireless power transmission structure isindependent from the display assembly, when the display assembly isdriven by a motor to rotate, a driving wiring that connects the wirelesspower transmission structure and the first driving power supply does notinfluence the rotation of the display assembly, thereby achieving a gooddisplay effect of the display device.

The circuit assembly 108may include a first support plate 1081, a circuit board 1082, a secondsupport plate 1083 and a support shaft 1084.

The circuit board 1082 is disposed between the first support plate 1081and the second support plate 1083, and the first support plate 1081 isfixedly connected to both the circuit board 1082 and the second supportplate 1083. A side, distal from the second support plate 1083, of thefirst support plate 1081 is fixedly connected to the display assembly101, and a side, distal from the first support plate 1081, of the secondsupport plate 1083 is fixedly connected to the receiving plate 10421.The side, distal from the first support plate 1081, of the secondsupport plate 1083 is also fixedly connected to the support shaft 1084,an axis of the support shaft 1084 is perpendicular to the second supportplate 1083, and the support shaft 1084 is disposed in the fourth throughhole 10421 a on the receiving plate 10421.

For example, the axis of the support shaft 1084 is collinear with anaxis of the fourth through hole 10421 a. In this way, stability of thecircuit assembly 108 which rotates with the display assembly 101 can beensured, and it can be ensured that the circuit assembly 108 can supplypower to the display assembly 101.

Optionally, the circuit board 1082 is fixedly connected to the firstsupport plate 1081 by screws. The second support plate 1083 is disposedat a side, distal from the first support plate 1081, of the circuitboard 1082, and the second support plate 1083 is fixedly connected tothe first support plate 1081 by screws.

Further, since the circuit board 1082 and the second support plate 1083are disposed on a same side of the first support plate 1081, anorthographic projection of part, configured to be connected to the firstsupport plate 1081, of the circuit board 1082 onto the first supportplate 1081, is not overlapped with an orthographic projection of part,configured to be connected to the first support plate 1081, of thesecond support plate 1083 onto the first support plate 1081. In thisway, the part, configured to be connected to the first support plate1081, of the circuit board 1082 and the part, configured to be connectedto the first support plate 1081, of the second support plate 1083 can beprevented from affecting each other, thereby ensuring normal operationof the circuit assembly 108.

Optionally, the circuit assembly may further include a flexible circuitboard (not shown in the figure) connected to the circuit board 1082, andthe flexible circuit board is connected to the display assembly 101. Thecircuit board 1082 is configured to transmit the power received by thewireless power reception structure 1042 to the display assembly 101 viaa flexible circuit board, so as to supply power to the display assembly101. Further, the circuit board 1082 may control display content of thedisplay assembly 101.

The heat radiation assembly 109 is furtherfixedly connected to the wireless power transmission structure 1041.

Since the second bearing 110 is sleeved on the support shaft 1084, thesecond bearing 110 can provide effective support for rotation of thesupport shaft 1084, thereby ensuring reliability of rotation of thedisplay assembly 101. Further, since heat generated when the displayassembly 101 rotates is high, the heat radiation assembly 109 can bedisposed to radiate heat in the housing assembly 102 to prevent thedisplay assembly 101 from being damaged due to excessive temperature,thereby achieving a higher yield rate of the display assembly 101.

In this embodiment of the present disclosure, the heat radiationassembly 109 is fixedly connected to the housing assembly 102, thewireless power transmission structure 1041 is fixedly connected to theheat radiation assembly 109, and the housing assembly 102 is not drivenby the motor 103 to rotate, and thus the heat radiation assembly 109 andthe wireless power transmission structure 1041 are not rotated.Therefore, when the motor 103 drives the display assembly 101 to rotate,the driving wiring connecting the wireless power transmission structure1041 and the first driving power supply may be in a stationary state,and the driving wiring does not influence rotation of the displayassembly 101, thereby achieving a good display effect of the displayassembly 101.
